The area of an heptagon = 4

Calculate side, perimeter

Calculate side:

A = 7/4s2cot(180°/7)

s2 =	4A
	7cot(180°/7)

s2 =	4 x 4
	7cot(25.714285714286)

s2 =	16
	7 x 2.0765213992964

s2 =	16
	14.535649795075

s2 = 1.1007419844018

s = √1.1007419844018

s = 1.0491625157247

Calculate Perimeter:

P = 7 x side

P = 7 x 1.0491625157247

P = 7.3441376100728

Calculate Sum of the Interior Angles:

Interior Angle Sum = (sides - 2) x 180°

Interior Angle Sum = (7 - 2) x 180°

Interior Angle Sum = 5 x 180°

Interior Angle sum = 900°

Calculate polygon diagonals

Diagonals =	n(n - 3)
	2

Diagonals =	7(7 - 3)
	2

Diagonals =	7(4)
	2

Diagonals =	28
	2

Diagonals = 14

Calculate 1 vertex diagonals:

1 vertex Diagonals = n - 3

1 vertex Diagonals = 7 - 3

1 vertex Diagonals = 4

Calculate triangles from one vertex:

Triangles = N - 2

Triangles = 7 - 2

Triangles = 5

Other Properties:

Sides (Edges) = 7

Faces = 1

Vertices = 7
